I am trying to use the getMapBoundaries method in my code, but the method is not defined.
Please note, I am for example able to use the animateToRegion method.

handleRegionChange = region => {
  //I get an error for the statement below
  console.log(this.map.getMapBoundaries())
};

//my MapView component
<MapView
    style={styles.mapView}
    ref={ref => {
      this.map = ref;
    }}
    onRegionChangeComplete={this.handleRegionChange}
    provider={MapView.PROVIDER_GOOGLE}
    showsUserLocation={true}
    showsCompass={true}
    showsScale={true}
    onMapReady={this.handleMapReady}
>
</MapView>

The version that has this method is not published yet on npm, use the git version.

psadeghian commented

Thank you for the response, the method now rejects due to the following reason:

undefined is not an object (evaluating '_reactNative.NativeModules.AirMapModule.getMapBoundaries')

Should I open a new issue?

rborn commented

getMapBoundaries is async, I use it like this:

onRegionChangeComplete = async region => {
        appStore.mapBoundaries = await this.map.getMapBoundaries();
...

also v0.23.0 was just published on npm so maybe you can try to update.

I did recognize the update, thank you!
I get the following error, could this be because I am using Expo?

@psadeghian yes, expo uses another version I think, you will need to wait for them to update or find a way to update it yourself

@rborn I am importing MapView from react-native-maps (I am not using the MapView provided by expo). I also tried using the git version.

@rborn I am having the same error: undefined is not an object (evaluating '_reactNative.NativeModules.AirMapModule.getMapBoundaries') I am using expo but have pulled v23 from github. What am I missing?

@psadeghian Did you figure this out?

Thanks,
Michael

@MichaelBalazs I am having the same error too. getMapBoundaries method seems to be not working on Android :(

Any updates here?

Android has issues:

I'm also having this issue, is there a solution for it yet?

thanks!

I use a manual solution to get boundaries for now.

I seem to be encountering this issue on Android but not iOS, currently running expo sdk35 with react native maps 0.25

iampeterbanjo commented

The root cause of this issue is with Expo sdk v35 and not react-native-maps. Using the same versions of react-native (0.59.10) and react-native-maps (0.25.0) as Expo (35), I can get map.getMapBoundaries to work without Expo which means something Expo is doing is causing the issue. See https://github.com/iampeterbanjo/react-native-v59-maps for an example of a working demo.

I have opened an issue at Expo

iampeterbanjo commented

@bkdev98 thank you for your workaround - it works but then I tried to use map.getCamera and that failed too for the same reason. :'-(

dragma commented

Same here. I need several methods of this MapView :'(
